Design and implementation of real-time scheduling algorithms for flexible manufacturing systems

摘要

>The objective of this research is to design and implement real-time scheduling algorithms for flexible manufacturing systems. Four CNC machines with a load/unload station and a conveyor belt are combined as a flexible manufacturing system. Three fuzzy-based scheduling algorithms have been developed for operation sequencing, task sequencing and routing. LabVIEW environment has been used for the system modelling and testing. Several case studies have been carried out to test and verify the flexibility of the system and the effectiveness of the proposed schedulers. The obtained results indicate that the proposed scheduling algorithms for sequencing and routing are promising for such FMS. The performances of the proposed fuzzy scheduling algorithms are compared with those obtained from published literature.
